i know ur goal here was to design ur own swarmer, but if want any of my designs just mail me in-game. since we are allied
id be happy to give u any of my swarmer designs. (i have about 30 different ones lol)
the bigger you go with swarmers, the more cost effective u get. although the smaller they are, the more bang u get for the fleet power.
if u are planning on defending with swarmers, i would suggest a superswarmer.
i dont want to really give out my tactics here, but mail me if your interested.
